Has the advantages that: the biochar is added after the primary fermentation, so that the leftovers of the livestock and the poultry can be decomposed, the reproduction speed of the microorganisms and the microbial inoculum is the fastest at the stage, and the biochar is added at the stage, so that the biochar can be prevented from being added and decomposed at the initial stage, and favorable conditions can not be provided for the reproduction of the microorganisms and the microbial inoculum well. Stirring is carried out at the later stage of fermentation, so that substances which are not completely fermented can be fermented, and meanwhile, the materials can be slowly crushed, so that the fusion of the biochar and the materials is realized, and the existence of granular biochar is reduced; and filtering the undecomposed residue and the incompletely pulverized biochar by filtration. And the filtered biochar can be reused, so that waste is avoided, and microorganisms and microbial inoculum are adsorbed in the filtered biochar pores, so that raw materials are provided for the next preparation of the organic fertilizer. The content of impurities in the formed liquid organic fertilizer is less, and the blocking condition during fertilization can be reduced.
Further, the rotating speed of the stirring rod is 200-250 r/min.
Has the advantages that: the rotating speed of the stirring rod is set, so that the biological carbon can be broken, a rotating force can be given to the biological carbon, the separation of microorganisms and microbial inoculum from the biological carbon is realized, and the quantity of the microorganisms and microbial inoculum in the subsequent filtered biological carbon is reduced.
Further, the stirring rod rotates intermittently, and the stirring rod rotates once every 30min, and rotates for 1-3min every time.
Has the advantages that: the biochar can be crushed through intermittent rotation, and meanwhile, in the crushing process, the fermentation liquor can also rotate along with the biochar, so that after the biochar rotates for a period of time, the stirring rod is not easy to contact with the biochar and further is not easy to completely crush, and the biochar can be stirred and crushed again after being settled through the intermittent rotation, so that the crushing effect is improved; meanwhile, the frequency of rotation is relatively low, and the influence on fermentation can be reduced.
